i To all whom it may concern: f

Be it knownthat we, N ELs'oNIhRAYMoNn and Jessen C. Verma-citizens ofthe United States, residingr at Brooklyn, New York, and `York,respectively, have invented certain new and useful lmprovc ments inElectrotherapeutic Apparatus, of

which the following lis a full, clear Vand exact description. y u

Our invention relates t'oelectro therapeutic apparatus, andyparticularlyto implements mtended to be used byyhandh The object of theinvention is to provide a simple and reliable apparatus the parts ofwhich may be heldin the twoy hands, and applied to such parts of thebody as may be def sired, while the current is` controlled by meansoperable by the thumbs of each hand. By this we do not wish itinferredthat the `apparatus cannotv be used in any other way.

It 1s, however, thc most convenient.

The invention consists in improvements the principles of 'which areillustrated in the accom anying drawings. 1t contemplates 'anlin uctionapparatus with a battery and co1 lThe apparatus comprises two members, I

each of which carries a suitable electrode for applying the secondary orinduced current. One member contains the battery and has a controllertherefor, while the other member contains the induction apparatus andhas a' regulator therefor.

'Figure 1 is a View of the a paratus cmbodyino* our invention, parts oiPthe same being bro :en away to show the interior construction. ,A Fig. 2is a fragmentary longitudinal sectional View of the part of theapparatus for turning on and off the rimary cur'- rent. Fig. 3 is across scctionaiiview of the the secondary current, the samebeing takenon the plane of the line X-.X Fig. 1. Fig. 4 is a detail view ofthecross bar 12. Fig. 5 is a View showing in dia am the wiring andelectrical connections in both members.

1 indicates the casing of the battery member, preferably of insulatingmaterial. 2 represents a suitable form of dry battery contained therein.3 represents one terminal of the battery. 4 is a screw taking intothefelectrode socket 5, and connecting it to the screw-threaded cap 6. 7is a threaded ring member carried by the casing 1, and to which isconnected the wire 8. 9 is a stationary contact member 'to which wire 8is f connected. 1 0 is a plate or base removably mounted in the case 1and affording` an abut.- ment for the spring 11, which affords tricalconnection withthe other terminalthe bottom Ol the cell 12 is a crossbar of insulating material, such as cbonitc through which the conductingwires pass. are screw posts rejecting from the plate 10 and to which eectrical connection is made beneath the bar 12. The spring 11 iselectrically connected to post 13. Post 14 is electrically connected bywire 15 to the longitudinally movable contact member 16. Contact is madebetween members 16 and 9 by depressing the member 16v for momentarcontact, or sliding it longitudinally beneat the lip of the contact 9for a prolonged contact, for instance, as set iorth 1n U. S. LettersPatent No. 780,523. ing and closing of the simply necessary to ho hand,and apply thethumbto the contact member 16.

The other member, the induction memrimary circuit, it is ber, of theapparatus is shown at the left in l the drawing. 17 represents thecasing which similarly toicasing 1, is formed of insu` lating material.18 represents the induction coil, containin r the primary and secondarywindings P an S. 19 and 20 represent the two heads of the spool of theinduction member. 21 and 22 are rods rigidly connecting the heads 19 and2O and serving as part of thel electrical circuit, the head 2() beingremovably secured in the casing. The two wires from the battery memberpass through the cross bar 23 and are secured to the ends of the rods.24 is a screw-threaded cap having a central opening for tho wircs Orconductor cable. .25 is a sleeve or tube longitudinally movable on thecoil 18 for varying the iield. 26 is a scale member carried by theladjusting sleeve 25 having a grooved portion guided by the rod 27. 28 isa pinion carried by the casing projecting slightly outwardly therefrom,and engaging on the interior with a rack 29, movab e with the scale andadjusting sleeve. The numbers on the scale are visible through asuitable opening. 30`rcprescnts'the armature mcmber'for the primarycoil. 31 is the adjustable contact screw, having a platinum point. Theprimary circuit passes through the two rods 21 and 22, through thearmature 30 and contact 31, so that when the current To operato theopen-A elec-y 13 and 14,

d 4the case 1 in thel is turned on in the battery member, it is repeatedly interrupted by the action of the ar- 36 and 37 representsuitable electrodes for applying the instrument to the body. The

secondary circuit when the instrument is applied, passes from theelectrode 37, through,

socket 5, cap 6, ring 7, Wire 8, contacts 9 and 16, Wire 15, thenthrough one of the Wires connecting the battery member to the inductionmember, thence through one of therods 21 or 22 tothe sprinvcontact 32,screw 33,

. socket 34 and electrode 36, andthen through such parts of the body asintervene betweenv the electrodes- 36 and 37.

LAs the inductionmember is grasped in the.

hand, the current may be regulated by a simple movement of the thumbupon the pinion 28. By this construction, the control of the primarycircuit and the regulation of the sec- 4 ondary circuit may beaccomplished by simi-4 lar movement, as the two members of theinstrument are 'held 1n the two hands of the operator. No confusion canthus arlse, and the primary current may be instantly turned on or oiilas desired, or the secondary current desired, at any time.

may be instantly increased or diminishedas The advantages of such anapparatus, besides those above pointedout, Will be apparent'to thoseacquainted with the operation and application of electro'therapeuticapparatus.

What we claim is:

1. 'As an article. of manufacture, a casing, 'a

removable cap at one end thereof, a battery contained AWithin saidcasing, a base plate, a spring interposed between the base plate andsaid battery, binding posts carried by said plate, a second capremovably secured to said casing and having a perforation for the passaev of electrical conductors.

- 2. n a device of the character described, a

combination of a casing, a battery member contained therein, allongitudinally movable contact member carried by said casing forcontrolling the battery current, a plate mounted in said casing, bindingpost carried thereby, and a removable cap carried by said casing havingan opening for the passage of electrical conductors.
